The said plates 11 directly` take the wear incidc'n to verticalmovements and endwise thrusting :now-mente of the bol.- stervin respectu the bolster mumns, and for ihis reason, :i1-v heiter than laterallyspaced guide. lugs or stops on the bnster wnont the connecing pute totake the direct wem'. Except for this latter noted reason, the inner 1miouter colnmn engaging Ezrefeably this truck boiser is in the form.

'il l.,

guide lugs on tin bolster might be completely separated or`:.li\":1lually formed.

` It is here important io malte the following observations: The bolstercolumns 3 are formed with bolster guiding surfaces 3* 'for engagementwith the guide plates 11, which terminate below the upper compressionmem bers of the coperating side frames a disv tance greater than thevertical dimensions of the said guide plates and of tbe track bolster,and said bolster columns above these bolster guidingr surfaces arespread or separated at 3" to an increased extent so that tbe bolster,when raised to an extreme position, may he removed endwise from thetruck side frames, through clearance passages 14, without requiringremoval from tbe truck bolster of the column engaging plates or lugs.This construction also permits tbe upper compression members of the sideframes to be cast integral with the cast bod)- portions of saidsideframes. It will be also noted that tbe bolster guiding surfaces of saidbolster columns are set farther apart than the extreme lower portions ofsaid columns so that a track bolster of as great, or even greater,extent, than the distance between the vertical flanges of the columnbase plates 6, may be emplo'fed. The springs 9 iyill be entirel relievedfrom tension when the truck olster is raised into position to` be movedendwise from the truck side frames through the widened clearance paagesM.

The truck bolster 10 has rigidly secured 1 to the end portions thereofroller bearing plates 15, located in the upper channels thereof, andor'medwitl. a multiplicity of roller seats extended longitudinallyof thetruck side frames and supporting lateral motion bearing rollers 16,t thecentral members of which, 'as shown are in the center planes of thecorresponding truck side frames. Uoon the rollers 16 is mounted aso-called floating or intermediate bearing plate 17, which forengagement with tle roller.` 16 has, in its undei surface, roller seatscorresponding to the roller seats in the plates 15, exce t that they arereversed or turned upside own. The bearing plates 15 and 1T andthe'inter osed rollers l all'ox-d the lateral motion d) presently to bedescribed. Otherwise stated. these lateral motion devices permit lateralmotion of the car body relative to the truck. ll, should be here statedthat. the roller bearing seats of the plates 15 and 17 are concave (theword concave being here :ised vin u broad sense) but their conoavitiesmay be formed either by a curve or direrging straight lines or planes,the well known function of which is to maintain tbe said plates 17 inintermediate position in respect to tte plates 15.

evices for permitting. endwise movements of the ear body bolster The carbody bolster 1S which, :is shown, has rigidly `ecured to its endportions .lcpending)r bcariuglegs It?, arranged in pairs and arranged toembrace the upper compression members ot the trucl: ide t1-unies withsufficient clearance to permit the required lateral motion of the carbody in respect to the truck. As slnm'n,`tl1ese pairs of bearing legs 19are cast integral with :i ric plate E20, whichz in turn, is rigidlysecured Lo tb:- body bolster bv means of rivets. 'l'lie lower ends ofthese bearing legs 1b rest upon and move with upper roller bearingplates 2l, between which and the intermediate bearing plate 11", sidehearing rollers 2:2 are interv posed. Preferably the upper rollerbearing plates' 21 are detachable from the bearing legs 19 but areintel-locked thereto by lugs 23 on the said plates 2l, which engage.notchesor seats in the lower portions of .said beziring legs. Therollers extend approxi mately at. right angles to the rollers 16 and arearranged to work in grooved flat-need seats formed in the said plateslt'and 2l, which seats, in plan, are curved on the arc of imaginarycircles struck from the axis of the pivotal connection betweentlie'truck and body bolster., Preferably also the upper or side bearingrollers 2. :irc arranged in two series with the rollers of the innerSeries axially a'lincd with the rollers of the outer series and with allof the said side bearing rollers propel-l",Y spaced b v a retaining cage24, of suitable construction, such for instance as that disclosed andclaimed in my o-pcndin;: application, S. X. 536.085. tiled ot' inteJanuary 3rd, 1910. and entitled Improved roller bearing. The rollersini-- ing cage is desirable in order lo keep the side bearinlgr rollersfrom bnnching und to keep the entire lot of rollers :l2 propel-lj,vcentered and positioned in respect to the bearing plates between whichthey work. The said .side bearing rollers are preferubi)v arranged intwo series with the inner and outer rollers axially alined. because therelatively short rollersl are better adapted, when.cylindrical, to worl:on a slight. are of u circle, than are rollers of much greater length.

The central.portions' of the trui-k und body holsters arepivoteilly'connected bv u suitable center coupling, which :illords theproper pivotal connection between the said parts and permits therequired limited lateral movements of the car bod)Y in respect to tbetruck and vice versa and allowsl all' the weight of the loud to bedelivered from the body holsters to the truck bolster und t e truck sideframes through the roller si e bearings and lateral motion devices. Precrably this center connection is subs.' .mtial of the form disclosed inmv .sind prior pate No. 863,012, of flute Auger# 13th. i907, n

comprises center plates' and 26, rigidly connected respectively to thebody bolster 1H and tbe truck bolster 10. The said plates 25 and Q6 havetelesooping or'interlocking 5 hubs 'of unequal size, the lmliof thelower plate 26 being considerably larger than the ub of the upper. plateand being also, as shown, of rectangular form, while the hub 0f theappel-,plate is of circular form. The two plates 25 and 2G are connectedby a king pin '27 closely fitted in the hub of the upper plate andworking in zin-elongated slot 28 in the lower plate. i

It should be noted that the roller bearing devices are located in theclearance passages but are formed inthe truck side frames immediatclybelow the upper compression members of the same and that they, therefordnormally hold the truck bolster down so that it cannot move, upward inalinem'ent of these clearance pxssages.
